... In the first page of this chapter, Eddington computes an effective temperature of 3.18 K, but this has nothing to do with the 2.725 K blackbody spectrum of the Cosmic Microwave Background (CMB) . Here is a quote of what Eddington actually said: . ... We shall first calculate the energy density of this radiation. ... It is clear that Eddington's model fits the optical data, but that Eddington did not anticipate either the CMB (red curve) or the interstellar dust (ISD, green curve). ...

... Future seminars . P a s t seminars . ... The heliospheric interface: theory and observations" . ... Sun is moving through warm ( ~ 6500 K) and partly ionized local interstellar cloud (LIC) with velocity ~ 26 km/s. Charged component of interstellar gas interacts with the solar wind (SW) forming the heliospheric interface, the SW/LIC interaction region. Both solar wind and interstellar gas have multi-component nature that creates a complex behavior of the interaction region. ...

... In 1930, Trumpler noticed that linear diameters (LD) of open clusters increase with distance (D) from the Sun. ... Since that time, the interstellar absorption has become one of the best studied factor in astrophysics, and we may hope that current OCL distance scales are free from this LD-D correlation. To verify if this is the case we have chosen several modern OCL distance scales and test them with the same clusters and the same angular diameters that Trumpler had used back in 1930. ...

... The solar wind streams off of the Sun at a speed of several hundred km/s, creating a magnetized bubble of hot plasma around the Sun. This bubble is called the heliosphere, and it is separated from the interstellar gas (local interstellar medium, LISM) by a heliopause. ... The heliopause is believed to be at least 120 AU away from the Sun, i.e., all the planets are located within it ( Earth and Pluto are 1 and 40 AU away, respectively). ...

... The Impact of HST on European Astronomy . ... These range from the study of nearby planets, the processes of star and planet formation, the stellar and interstellar components of galaxies, the discovery that most, if not all, galactic nuclei harbor a massive black hole that profoundly affects their evolution, to the realisation that the universe as a whole is undergoing acceleration as a result of a yet unknown form of dark energy . ...

... 1998: . The structure of neutral interstellar hydrogen emission at high galactic latitudes from 45 to 90 degrees was studied for the first time with the RATAN-600 at a wavelength of 21cm. The on galactic latitude dependence of the average characteristics of hydrogen distribution in the sky corresponds to the distribution of gas in the Galaxy in the shape of a flat layer. ...

... If the mass of the collapsing star is more than three solar masses, however, no force can prevent it from collapsing completely to become a black hole. What is a black hole? Mini black holes . ... For Further Reading About Black Holes A black hole is a region of space in which the pull of gravity is so strong that nothing can escape. ... A black hole with a mass less than three solar masses would not form on its own; its gravity is too weak to cause it to completely collapse in on itself. ...
